WEIGHING SCALE.

Application led April 1, 1926.

This invention relates to an improved weighing scale, and it has more particular reference to advertising means to be used in association with the scale.

Briefly7 the invention has reference to a scale structure wherein the standard is in the form of a vertically elongated casing of substantially rectangular form, this casing being provided on its interior with drums over which an advertising band passes. The

front of the casing is formed with an opening through which the advertising spaces or areas on the band are successively displayed. In the casing is arotatably mounted weight indicating disc which is operated from a tiltable plat-form through the medium of rack and pinion means; Manually operated means is provided and disposed on the exterior of the standard for rotating the upper drum to operate the advertising band.

Then there is a novel means between the shaft of the upper drum and the rack bar for controlling the action of the rack and pinion.

The principal object is to provide an especially constructed device between the shaft of the upper drum and the rack bar so that the rack bars cannot be operated until the drum is turned to aset position by a hand 30 crank, thereby making it compulsory to turn the drum to change the advertising space in order to permit operation of the weight indicating disc.

The features and advantages of the particular construction employed will become more readily apparent from the following description and drawing.

In the accompanying drawing forming a part of this application and in which like numerals are employed to designate like parts throughout the same:

Figure 1 is a fragmentary view in section and elevation showing a part of the scale constructed in accordance with this invention.

Figure 2 is a detail View showing latch mechanism.

Figure 3 is an enlarged view of a part of the latch mechanism.

Before proceedingr with the detailed description, attention is called to the fact that the present invention embodies features of construction shown in Patent No. 1,570,872 granted to me on January 26th, 1926, and a 55 copending application Serial No. 52,806 filed by me on August 27th, 1925. It is believed Serial No. 99,057.

that reference should be had to these patents before consideringthe present case.

Referring to the drawings and particular to Figure 1 it will be seen that the reference character 1 designates generally the vertical portion of a casing or weighing scale standard. This is of general rectangular configuration. Mounted in the top of the casing on a shaft 2 is a rotary drum 3. At one end of the shaft a crank 4 is formed and has its end portion disposed on the exterior of the casing to accommodate a handle 5 by means of which the drum and shaft are rotated. Trained over this drum and also over a similar drum (not shown in the modification) is an endless advertising band divided into a plurality of advertising areas `or spaces 6. A coiled spring 7 is connected by a link 8 to the crank 4 and is then connected with a stationary bracket 9 and serves to maintain an advertising space 6 in proper position for display. By referring to previous patents it will be seen that the casing is provided at a predetermined point with an opening or window with which this advertising space is adapted to register so that when a person stands on the platform of the scale, they can view the advertisement through the window. At the opposite end of the shaft is a depending arm 10 terminating in a head 11.

Mounted in guides 12 at a point below the shaft and arm is a reciprocating control rod I 18 having its lower end portion 14 directed at right angles and engage beneath a shoulder 15 on a toothed rack bar 1G. The teeth of this bar mesh with the teeth of a rotary pinion 17 which serves to impart rotation to arotary weight indicating disc 18.

At this time I would state that in practice the periphery of this disc 18 is provided with weight indicating numbers which are displayed in an appropriate manner. Moreover the lower end portion of the rack bar 16 is connected with a tiltable platform forming a part of the base of the scale structure, and when this platform is tilted downwardly under the weight of the person, the rack bar is moved downwardly to rotate the pinion and to in turn rotate the weight indicating disc. It will be noted that a yoke 19 is associated with the pinion 17 and has its bight portion confined in a slot 20 in the rack bar.

Referring now to the upper portion of the control rod 13 it will be seen that a. collar 21 is carried thereby and a coiled spring 22 surrounds the rod betiveen the collar and the iipperniost guide 12. VEhen by directing attention to Figure 2 it ivill be seen that the spring` pressed latch 23 is carried by the npper end ot this rod and is adapted to he engag'ed With the head 11 on the arin 10 to inaintain the rod 13 in the position slioivn to prevent doivnivard inoveinent ot the rack bar 16 and consequent operation of the scale indicating` ineans.

In accordance ivith this invention it is compulsory in order to perinit operation oit the indicating disc 18 to release the rack and pinion mechanism. To do this the person standing on the scale nnist necessarily tnrn the hand crank 5. In so doing the rotary drinn 3 at the top will he rotated and this will disengage the head 10 Jiii-oni the latch 9.3, thns letting' the control rod 13 nieve downwardly with the rack bar and to perinit consequent operation ot the indicatingl disc. According to the instructions, the hand crank ivill have to be turned a coinplete revolution and in so doing, a` nen' advertising space 6 will be brought np tor display7 purposes. In this ivay a tiill benefit ot the advertisinginediinn will be obtained. The spring ineans will reset the latch, and the latch ivill be reengaged with the head 11 after the latter has been returned to its nornial position by a t'iill rotation ot the drinn.

It is believed that the advantages and featiires oi' construction of an invention ot this hind will be clear to those skilled in the art to ivhich the invention relates after consid ering the description in connection 'ith the drawing, therefore a inore lengthy descripw tion is thought unnecessary.

IVhile the preferred einbodiinent ot' the invention has been shoivn and described, it-

is to be understood that minor changes coining' ivithin the iicld of invention claimed may be resorted to it' desired.

Having thns described the invention, ivhat I claiin as newv and desire to secure by Iict` ters Patent is 1. In a strnctnre ot the class described. in combination, a casing, a drinn rotatably mounted in said casing, an advertising band trained over said drinn, a ivcigljht indicatingr incans in said casing, operating ineans for said Weight indicatin means, and a control device cooperable ivith said drinn and said o ierating ineans, ivhercby it is necessary to niove the drinn to'predeterinined position to perinit said operating nieans to operate.

In a strnctiiie of the class described, a vertically elongated casing, a shaft rotatable in bearing in sait;L casing, niannally operable ineans tor rotating said shait. a drinn inonntcd on said shat, an advertising band trained over said drinn, an indicating disc inonnted for rotation in said casing, operatingl ineans for said disc, and a control device cooperable with said shaft and with said operating` means.

3. In a weighing scale structure of the class described, a casing, a shaft mounted for rotation ivith said bearings in said cas ing, a drinn on said shat't, and an advertising band trained over said drinn, a hand crank tor rotatingr said shaft, nieans for maintaining said shaft in a n'orinal position, a rotary indicating disc, rack and pinion ineans cooperable with said disc for operating it, and a control device between said shatt and said rack and pinion ineans, said control device includingl a slidably mounted rod, a latch mechanism cooperable there With and With said shaft.

In testimony whereof I aifix iny signature.

PHILIP VIVIANO.
